mpc83xx: add support for the MPC8323E RDB
MPC8323E based board with 64MB fixed SDRAM, 16MB flash, five 10/100 ethernet ports connected via an ICPlus IP175C switch, one PCI slot, and serial. Features not supported in this patch are SD card interface, 2 USB ports, and the two phone ports.

Freescale MPC8323ERDB Board

-----------------------------------------
|
||||
|
||||
1. Memory Map
|
||||
The memory map looks like this:
|
||||
|
||||
0x0000_0000 0x03ff_ffff DDR 64M
|
||||
0x8000_0000 0x8fff_ffff PCI MEM 256M
|
||||
0x9000_0000 0x9fff_ffff PCI_MMIO 256M
|
||||
0xe000_0000 0xe00f_ffff IMMR 1M
|
||||
0xd000_0000 0xd3ff_ffff PCI IO 64M
|
||||
0xfe00_0000 0xfeff_ffff NOR FLASH (CS0) 16M
|
||||
|
||||
2. Compilation
|
||||
|
||||
Assuming you're using BASH (or similar) as your shell:
|
||||
|
||||
export CROSS_COMPILE=your-cross-compiler-prefix-
|
||||
make distclean
|
||||
make MPC8323ERDB_config
|
||||
make
|
||||
|
||||
3. Downloading and Flashing Images
|
||||
|
||||
3.1 Reflash U-boot Image using U-boot
|
||||
|
||||
N.b, have an alternate means of programming
|
||||
the flash available if the new u-boot doesn't boot.
|
||||
|
||||
First try a:
|
||||
|
||||
tftpboot $loadaddr $uboot
|
||||
|
||||
to make sure that the TFTP load will succeed before
|
||||
an erase goes ahead and wipes out your current firmware.
|
||||
Then do a:
|
||||
|
||||
run tftpflash
|
||||
|
||||
which is a shorter version of the manual sequence:
|
||||
|
||||
tftp $loadaddr u-boot.bin
|
||||
protect off fe000000 +$filesize
|
||||
erase fe000000 +$filesize
|
||||
cp.b $loadaddr fe000000 $filesize
|
||||
|
||||
To keep your old u-boot's environment variables, do a:
|
||||
|
||||
saveenv
|
||||
|
||||
prior to resetting the board.
|
||||
|
||||
3.2 Downloading and Booting Linux Kernel
|
||||
|
||||
Ensure that all networking-related environment variables are set
|
||||
properly (including ipaddr, serverip, gatewayip (if needed),
|
||||
netmask, ethaddr, eth1addr, rootpath (if using NFS root),
|
||||
fdtfile, and bootfile).
|
||||
|
||||
Then, do one of the following, depending on whether you
|
||||
want an NFS root or a ramdisk root:
|
||||
|
||||
run nfsboot
|
||||
|
||||
or
|
||||
|
||||
run ramboot
|
||||
|
||||
4 Notes
|
||||
|
||||
The console baudrate for MPC8323ERDB is 115200bps.
